When Middlesbrough plasterer Glenn Melvin decided to take a new direction after 25 years in the trade, he looked to the growing market for thermal insulating render. After studying up on thermal standards and experimenting with a range of mix designs, Melvin has established Walltransform and developed the Wallreform render.<p></p><p> The render is designed to be trowel or spray applied internally or externally to a depth relative to the desired level of thermal insulation, ranging from around 12-15mm for regular or anti-condensation plaster to 40mm plus for additional efficiency. It is available in a range of finishes, including brick effect. Wallreform is now Board of Agrement certified, and has made its way onto the Energy Saving Trust&amp;’s website as a recommended external insulant. </p><p> Melvin says: &amp;“Because I was a plasterer working for myself I had time to spend on experimenting with various mixes until I got it right. I suppose bigger companies have not done this because they don&amp;’t really want to spend money hiring a plasterer just to fiddle around with obtaining mix designs.&amp;”</p><p><br> </p><p><b><b>Key contacts</b></b><br><b><b>Almura Building Products 01242 262 900</b><br> Eternit Building Materials 01763 264 600</b></p><p><b> Finnforest 0800 00 44 44</b></p><p><b> Lafarge Cement 01235 448 400</b></p><p><b> Sto …
